Infiniti has unveiled its future contender for the luxury SUV market by unwrapping the new QX Sport Inspiration concept in Beijing.

The mid-sized premium SUV points to a rival to popular models such as the Audi Q5, helping Infiniti branch out as part of an ongoing model expansion locally that will include the compact Q30 and QX30.

The concept takes a different path to the fluid, organic lines of the QX70 SUV by adopting a blockier, more purposeful form.

Its styling is said to be an evolution of the brand's "Powerful Elegance" design language that features on the upcoming Q60 coupe.

Infiniti says the car has plenty of ground clearance, and that its 2800mm wheelbase ? on par with the current Q5 or BMW X3 ? offers plenty of interior space.

The interior features four main seats with a fifth flip-down chair for occasional use, and a driver-focused cockpit with minimal buttons and two large digital screens.

The carmaker says its concept "hints at a future Infiniti mid-sized premium SUV", though it is not clear when such a model will reach showrooms. The brand unveiled the similar-sized QX50 at the 2015 New York motor show but Infiniti Australia decided against offering the car locally.
